ber 15. The end 22? of the pipe'22 within the i This invention pertains to air heaters, moisteners and purifiers of the class calcu lated'to effect the temperature of buildings, rooms and apartments and has for its object to provide construction that will not only effeet the desiredtemperature but will also regulate the quality of the atmosphere,maintain ing the same free from dirt, dust, "gases or other undesirable elements.

The objects of the inven't'on are attained by generating steam and c rculating the same through coils enclosed in an-airheating chamher and forcing a circulation of air through said chamber and around the coils, thence through therooms or apartments and thence,

back through the chamber and around the coils, moistening and purifying the same in transit beforethe air re-enters said chamber.

Steam may be generated by any form of heat desired, but if fuel, other than electricity is used, the heating should always be done outside of the chamber in which the coils are situated, and provision made for carrying away the fumes. i

The invention will be hereinafter particularly described, illustrated in the accompanying drawings and pointed out in the appended claims. In the illustration of the invention herein described, the manner of heating will be by electricity.

In the accompanying drawings, Fig. 1 is a side elevation of the invention and Fig. 2 is a central vertical sectional view, partly in elevation.

In a detail description, in which like numerals refer to like parts throughout the several views, an air heater in the form of a cylinder 10 provides an air heating chamber within which is mounted a pair of coils 11 annularly disposed therein. Centrallyidisposed within the heating chamber and inside the coils 11 is a cylinder 12, not necessarily hollow, but.

proportioned to occupy a large portion of the space within the annular coils11. A wall 13 having perforations 14, forms the bottom of the heating chamber and the top of moistening chamber 15. Adjacent the heating chamber and the chamber 15 is mounted a boiler 16 ing elements 17 Water 18 in the boiler submerges t 1e elements 17 A water supply pipe 19 connects with the boiler 16 at20 and has a valve 21 for the purpose of regulating the water level within the boiler. A pipe 22 leads from the pipe 19 and connects with the chamwithin which are mounted electric heat chamber 15isprovided with aspray nozzle .23.. A valve 2 1 regulates the supply of water to the pipe 22 and the nozzle 23. A waste pipe 25 connected with the chamber 15, with the lower edge of the opening therein about one lnchabove the bottom 26 of the chamber,

15, and maintains a water level27 within the I chamber15, of about one inch at all times. A

tached to the boiler 16indicates the water level therein. Leading from the steam spaces of the boiler 16is asupply conduit 33 connected with the tops of the coils 11. Attached to the conduit 33 is a steam gage 34. Mounted adjacent the heating chamber and along horizontally disposed conduit 36 connected therewith and leading to the chamber 15.

Also connected with the fan is a vertically disposed conduit 37 at the top of whioh is mounted a drum 38. Heat distributing pipes 39 of relatively large size lead from the top of the heating chamberand relatively small 5 air intake pipes 10 connect with the drum 38. vIn-1:)ractice the latter pipes are smaller than the former, as the same receive the cooler air while the former distribute the heated air. 1

In the practical application of the invention'and taking for an example, the heating of an ordinary five room cottage, the appa-v ratus is mounted in the basement with one of each of the pipes 39 and 40 connected with each room to be heated. Sufficient water is supplied through the pipe 19 to the boiler 16 to measure abouttwo gallons and the valve 21 side of the chamber 15'is a fan 35 having a I is closed. The valve 24 in the pipe 19 is ad- I justed to permit a light spray of water to pass through the spray nozzle 23 into the chamber 15. Current is supplied to heat the ele- 'ments 17 through the connection 411'. Current is supplied to the fan 35 through the connection 42. Steam generated from the boiler 16 passes through the conduit 33 and into the tops of the coils 11, forcing the air in the coils downwardly andout throughthe vent 30. Steam condensed in the coils 11 and in the conduit 28 returns to the water spaces of the boiler 16-and is used over and over again, it being unnecessary to add to the Water suply in the boiler oftener than once each week. After the water has once been turned into steam, the same becomes distilled and does not corrode or otherwise obstruct the coils or pipes. The fan installed in this instance has a capacity of eighty cubic feet a minute, thereby drawing eighty cubic feet of air a minute from the rooms through the pipes 40, drum 38, pipe 37 and forcing the same through the conduit 36, chamber 15, heating chamber and out through the pipes 39 back to the rooms. In the passage of the airthrough the chamber 15, the same is Washed and'purified by the spray of water from the nozzle 23, thereby furnishing a clean, healthful atmosphere to the rooms. With the capacity of the fan mentioned, the air in the rooms is substantially com- 'pletely' changed and renewed every eightyiive minutes or so. The cylinder 12 extending vertically through the heating chamber forces the air passing upwardly through the perforations '14 into close contact with the coils 11, thereby aiding in obtaining the maximum amount of heat from the coils 11.

'lheinverted cone 43 at the top of the heating chamber directs the circulation of the air toward the pipes 39. One hundred and ninety-eight degrees of heat is obtained at the entrance to the pipes 39 by the construction shown.

What We claim is:

In an air heater, a heating chamber, a plurality of coils mounted therein, a member positioned within thecoils and spaced there- 7 tributing pipes from the heating chamber,

and an inverted cone-shaped member positioned at the top of the heatingchamber for deflecting the heated air into the distributing pipes.
